WebMay 1, 2012 · The symmetrical OTA was successfully verified in a standard CMOS 0.35-μm process. The measurements show an open loop gain of 61 dB and a unit gain frequency of 195 Hz with only 800 mV of power supply voltage and just 40 nW of power consumption. WebJul 1, 2024 · 3. Class-AB OTA based on adaptive biasing. The adaptive biasing circuit shown in Fig. 3 has been exploited to design a fully differential class-AB OTA: a symmetrical OTA topology has been adopted, since it requires a single bias current source, thus it can be easily biased by the designed adaptive bias circuit. Moreover, the symmetrical OTA …
